Hi,
A while ago I noticed that the map of the origin of the artist stopped adding bands and I think it is not counting the new scrobbles either. I don’t know if this problem has already been reported, but I share it in case it is not the case.
I am having the exact same problem - I had noticed it sometime in September, perhaps mid-September, and I had intended to post on this last week but was busy at work and now found some time to come here and am relieved to see someone else has done so.
One of the patterns I seem to notice is that sometimes the system will log a single play, but in reality there have been 30. Other times they are completely MIA. However, I just saw that my map for September has updated somewhat. I am theorizing it might be a lag in the system.
I also notice other anomalies - like artists that appears for ‘last month’ in a country that has zero other artists I listen to, but does not appear for ‘this year.’
